Another important object of the invention is to provide the cabinet with ventilation features whereby the room for which the cabinet is installed may be ventilated and the-ventilation controlled by the occupant without sacrificing privacy of the room.

In accomplishing these and other objects of the invention, 1 have provided improved details of structure, the preferred form of which is illustrated in the accompanying drawings, wherein:

Fig. 1 is a perspective view of the corridor side of a cabinet constructed in accordance with my invention and illustrated asinstalled in a door, the service door being shown in open position to better illustrate the compartments and their guard doors. i Fig. 2 is an enlarged vertical sectional view on the line 22, Fig. 1.

Fig. 3 is a perspective view of the room side of a cabinet in position ready to be installed inadoor. V

Referring in detail to the drawings:

1 designates the cabinet frame, preferably rectangular in shape, and including side members 2 and 3 and top and bottom members k and 5, respectively, the top and bottom mem- 1928. Serial No. 294,280.

bers being joined to the side members as in standard cabinet practice. The frame thus constructed is divided by spaced horizontal partitions 6 and 7 to provide superposed article receiving compartments 8, 9 and 10 which are enclosed by front and back panels 11 and 12, each panel comprising a fixed section 13 and a hinged door section 14.

The fixed sections of the panels are located at opposite diagonal corners of the cabinet and are secured to the frame members by rabbet joints 15 comprising tongues'l6 projecting from the edges of the side frames and received 1n grooves 17 formed 1n the panels.

The fixed sections preferably extend midway across the face of the cabinet so that their inner'edges 18 align with relation to each other and door openings 19 and 20 produced etween the inner edges of the fixed sections I and the adjacent sides of the cabinetare 0&-

set to eachother for preventing direct observation or access through the cabinet at the v door openings. Thus each door opening d1- rectly faces the fixed section of the opposite panel.

The door sections are hinged to the free in- I ner edges 18 of the fixed panels preferably by piano hinges 21 which extend the entire length of the door and panel sections, to provide a closed and sound-proof joint therebetween.

The door sections are of suflicient width to overlap the face edges 22 of the cabinet frame and preferably close against felt stripping 23 received in grooves 24 of the edges 22, providing for silentclosing of the door as well as providing a tight sound-proof joint.

The cabinet thus far described may be provided in various sizes and installed in doors or walls separating the room from a corridor or exterior of the building so that articles may be inserted through one of the doors from a position exterior of the room and removed through the other door from aposition interior of the room, and vice versa. However, the cabinet illustrated is of a type and size to be installed in a door and is substituted for the ordinary door panel as now described.

The door 25 is of ordinary construction I and comprises the hinging stile 26, lock stile 27, and top and Qottom rails .28 and 29, re-

spectively, forming a rectangular opening 30 to receive the cabinet just described so that sides or" thedoor to provide a balanced structure.

The .cabinet is secured in the dooropening by stops 31 and 32 extending peripherally 7 may be controlled from the room side of the around the cabinet at each side of the door,

the stops 31 being preferably inserted with in grooves 33 produced in the outer faces of the cabinet frame and the stops 3?. being preferably secured to the door by nails 3% driven through the stops and into the door. The cabinet is further secured to the door by screws 35 which are projected through the cabinet frame and into the door at intervals around the cabinet frame, shown in 2 an d 4 p The doors of the panels are provided with latches '36 and 37 for the respective doors at both sides of the cabinet and each latch comprises an arm 38 fixed to an actuating shaft SQ-IOtatably :mounted in an opening 40 in the cabinet frame, the arm38 being provided with a rectangular aperture 41' to receive a hook secured to the respect-ive doors by screws 43. The latchclever arm and heck are enclosed by a housing 44 secured to the cabinet frame by screws 45 and provided with an open side 46 to receive the'hook 42 to latch the door in closedposition. The shafts 39 of the locks may be actuated by handles 47 at the sides of the frame.

While I have desc ibed the door latchesin substantial detail, it is reac various type locks or latches may be employed and I do notwish to be limited to the exact detail shown anddoseribed; .In order to provide each of the compartments with independent locking means which door and automaticallylocked by a servitor from'the corridor side, I have provided each of the compartments 8,9, and 10 with individual sliding guard panels 4-8, 49 and '50, re-

spectively, adapted toclose the compartments against access from-the corridor'side after articles-have been placed therein pending removal by the room occupant.

Each guard preferably comprises a perforated metallic plate 51, substantially the width of the door opening and of suitable height to close the openings between the horizonta'l partitions. The top and bottom edges of the plates are rolled to provide tubular guide members 52 and 5,3 which are sleeved on guide rods 54 and 55 extending across the cabinet and fixed to the side frame members by plates 56 attached to the ends of the rods and secured to the side members by screws 57, as best shown inFigs. 2 and 8. V

The guards are also provided with rolled side edges 58 and 59 and with a slot 60 adjacent its outer end to provide a finger hold for apparent that assisting in sliding the panel along the guide rods to open or closed position. The guard panels are adapted to be looked in closed position by latches 61 pivotally suspended in latch housings '62 which are inset in the inner side 01" the fixed panel on the corridor side and'are secured thereto by screws 63. The

latches are pivoted at their upper ends on.

oins 64 carried b 1 the housing" and the centerof gravity of the latches is such as to retain a pro ecting lug G5 on the lower end thereof normally in the path of the guard" panel, so'th'at when the panel is closed, the lug Wlll move outwardly of its housing and engage rearwardly oi the guard to prevent its being opened until the lug is again moved into the housing to free the panel. This can only be accomplished from the room side-of the cabinetas will be later described;

As before stated it is also a purpose of this invention to provide means whereby the room may be ventilated through the cabinet as now described.

The corridor door designated 66 1s provided with a rectangular opening 67 enclosed with a plurality of louver slats 68 angularly disposed across the opening and arranged in spaced relation to provide openings 69 therebetween for ventilation, but which, due to their angular arrangement, will obscure di-J' equal to area of the door opening, the fixed panel designated 71 of the corridor side is also provided with a louvered opening 72' similar to the corridor door, thus providing maximum air passage through the cabinet. It is apparent that snce'the guard panels are perforated as described, they will offer little obstruction to ventilation through the cabinet.

cipally for replacing the ordinary door panel, it is apparent that the cabinet may be constructed as a part of a door or it may be readilyins'talled ina special wall opening constructed to'receive it.

In operation of the cabinet the guard panel's will normally be moved to the'rear of the fixed panel 71, leaving the entrance to the compartments open, except for the door 66. When a servitor wishes todeposit an article in one of the compartments, he will through the i \Vhile I have described thecabinet prinedge of the door to prevent its again being opened until released by the room occupant. Thus the servitor locks only the compartment used, leaving the other compartments open for receipt of other articles. Then the occupant Wishes to remove the deposited article, he will open the room side door 70, re-

move the article, and move the guard to open position by depressing the latch and slid- 1O ing the guard along the guide rods, again preparing the compartment for further deposits.
